to this species, although it shows some discrepancies from

Snout short, obtuse, but rather longer than the eye, with
the mouth at its lower side. Mouth narrow, a little wider
than the eye, armed above and below with six notched teeth ;
its corner lies a little in advance of the vertical from the front
margin of the orbit. The upper profile of the head is somewhat
more convex than the lower and ascends slightly towards
the origin of the dorsal. Eye one-fifth of the length of the
head. The height of the body is contained 3f times in the
total length (without caudal), the length of the head 5 \ times.
Caudal peduncle extremely slender, longer than the head
(measured from the last anal ray), its depth being only two-
ninths of its length. The origin of the dorsal fin is behind
that of the anal and midway between the root of the caudal
and the end of the opercle. The anal extends also further
backwards than the dorsal. Pectoral fin as long as the head,
reaching beyond the middle of the ventral ; ventral fin half as
long as the pectoral or as the distance of its root from the
vent. Abdomen behind the ventral fin compressed into a
ridge. Scales of moderate size ; there are nine in an oblique
series running from the vent to the lateral line and three and
two half longitudinal series . cover the side of the caudal
peduncle. Silvery, light brownish above..
